Specification of Letters Patent.

Patented May 23, 1922.

Application filed. August 8, 1921. Serial No. 490,742.

' sheets of glass such as clear panes, mirrors or wooden panels when disposed in frames and when resting in the rabbets provided therefor, and has for its object to simplify and cheapen the construction of the device;

to increase the service length thereof; and to eliminate the moisture which accumulates between the g'lass or panel and the holder; and a particular object is to improve the construction disclosed in the United States Patent No. 1,155,924, granted to me under date of October 5, 1915, for improvements in glass or mirror fasteners, to which patent cross reference is here made.

Description.

The structure disclosed in the patent above referred to had certain objections, among which may be numbered the fact that it has been difficult, and consequently expensive, to manufacture the guides for the fastening member or nail with which the same has been provided, which guides have not been sufficiently strong to avoid the accidents incident to the turning or bending of the nail or fastener when being driven. Also the protuberances shown as a part of the construction of this form of the fastener have provided insufficient foundation to resist pressure on the opposite side of the glass.

To avoid these various difliculties, I now make a relatively solid pad 11, in the under face of which I sink shallow sockets 12. The pad 11 is elongated and has extended from the under face a retaining edge 18. The edge 13 generally protrudes beyond the under face of the pad a distance equal to the thickness of the glass 14: which it is sought to mount in the frame 15. The edge 13 also fills the space between the edge of the glass 14 and the side of the rabbet with which the frame 15 is provided.

The pad 11 has on the upper side, and disposed lengthwise thereof, a guide groove 16, which serves to guide the fastening member or nail 17 throughout its entire length. As seen best in Figures 1 and 2 of the drawings, the fastening member or nail 17 rests full length in the groove 16, to be guided and supported thereby when and during the driving of the fastening member or nail 17 into the frame 15.

The pad 11 is preferabl constructed from a relatively soft fiber. A hesively secured to the top surface and adjacent the forward end thereof is a resilient retainer strip 18. The strip 18 covers the groove 16 at the forward end of the pad 11, and frictionally engages the fastener to hold it in the groove 16 and on the pad to which the member is attached, to prevent the same from falling out or becoming separated from the pad.

The pads 11 are preferably manufactured in groups, as seen best in Figure 6 of the drawings. It is obvious that whereas in the said Figure 6 a group of three is disclosed the number-of units inthe group may be indefinitely multiplied. The separate members or pads 11 are partially severed by scoring or cross cuts 19, which partially but not completely sever the pads one from another.

It will be understood that the pads are manufactured and sold on the market in the groups, and that when it is desired to use one or more of the pads, they are torn successively from the group and then placed in position upon the glass 14: at the back thereof, with the edges 13 of the various pads extending between the edge of the glass 14 and the side of the frame 15 to cushion and support the glass in the said frame. The nails 17 are then driven into the frame without being lifted from or otherwise dislodged from the grooves 16. During the operation of driving the nails or fasteners 17 the strip 18 holdsthe fastener in the groove 16, and prevents any accidental dislodgment or loss of the fastener by reason of the same being snapped out of the said groove and out of engagement with the said pad.

In service the sockets 12 serve to retain any moisture which may accumulate while preventing expansion of the pad at the contact surface thereof. Any swelling of the material is taken up by the interstices formed 'by the said sockets.

Claims.

1. A fastener as characterized comprising a pad; a fastening member disposed prone thereupon for extending from one end thereof; and a resilient cover therefor, said cover and pad having a passage therebetwcen for said fastening member.

2. A fastener as characterized comprising a pad having a groove formed in the exposed surface thereof; a fastening member disposed prone in said groove; and a resilient cover for said fastening member, said cover being connected to said pad. 7

3. A fastener as characterized comprising a pad having a guiding groove in the exposed surface thereof; a driving nail disposed prone in'said groove; and a resilient detent monnted in said pad for pressing on said nail for holding the same in said groove. 7

at. A fastener as characterized comprising a pad having a guiding groove in the exposed surface thereof; a driving nail dis posed prone in said groove; and a resilient 6. A) fastener as characterized comprising a pa d having a guiding groove in the exposed surface thereof; a driving nail disposed prone in said groove; a resilient cover strip mounted on said pad for frictionally engaging said nail for restraining the same from 'dislodgment from said groove; and

means for preventing the warping of said pad, said means embodying a series of sockets formed in the under surface thereof.
